Lupin bean
A protein-rich edible seed of a lupin plant, eaten whole or ground into flour. Bitter varieties require processing to remove quinolizidine alkaloids.
Lupin flour: A flour made from lupin seeds, used to enrich foods with protein and fiber. Grinding lupin beans creates a gluten-free ingredient for breads, pasta, and other foods.
Quinolizidine alkaloids: A class of nitrogen-containing compounds found in lupins and other plants, including compounds with toxic effects. These bitter compounds are the main reason many lupin seeds need debittering.
Legume: A plant in the family Fabaceae, whose members commonly bear seeds in pods. Lupins are legumes, sharing broad seed and crop traits with peas and beans.
Lupinus mutabilis: A lupin species domesticated in the Andes for its edible seeds, commonly called tarwi or Andean lupin. Tarwi is a traditional food lupin whose seeds are eaten after debittering.
Soybean: An oilseed legume cultivated for food, animal feed, and industrial products. Soybean is a more widely used high-protein legume competing with lupin in foods.
Lupin bean snack: A prepared lupin seed eaten whole, often brined and served as a snack. Whole beans are a traditional food in Mediterranean and Latin American cuisines.
Debittering: Food processing that reduces bitter-tasting compounds in an ingredient. Soaking, boiling, and rinsing can leach alkaloids from lupin seeds.
Seed: A plant structure containing an embryo and stored resources for its development. The edible lupin bean is the seed of a flowering plant.
Lupinus luteus: A yellow-flowered lupin species cultivated for seed, forage, and soil improvement. Yellow lupin is one of the species used as a crop for edible seed.
Chickpea: A round edible pulse from the plant Cicer arietinum, also called garbanzo bean. Chickpeas are another flour-producing pulse, but have a different flavor and composition.
